Responsibilities
Own the messaging platform end to end (ingestion, orchestration, templating/rendering, scheduling, routing, send, feedback loops, analytics)—with clear SLOs, scalable multi-region architecture, and a measurable reliability posture (e.g., error budgets, MTTR, incident rate)
Increase deliverability & throughput by advancing our MTA/SMS provider strategies, queueing and rate-limiting, channel-specific features (e.g., pre-flight checks, warm-up), and feedback processing (bounces, complaints, carrier responses)
Harden compliance & safety in partnership with Legal/Privacy (e.g., consent/state management, opt-out, quiet hours, TCPA/CAN‑SPAM/CTIA/GDPR-aware workflows) to protect customers and their end-users
Accelerate developer velocity for channel teams via clear APIs, SDKs, contracts, documentation, and paved-road tooling (test environments, canaries, shadow traffic, feature flags, progressive delivery)
Deliver business impact by tying platform choices to measurable outcomes (deliverability %, send latency, success rate, $/MM, cycle time), setting an annual platform strategy and quarterly commitments
Build and scale a high-performing org of managers and senior ICs; raise the talent bar through crisp expectations, transparent feedback, and career growth paths aligned to Klaviyo’s standards
Transform workflows with AI. Put AI at the center of how the org plans, operates, and learns—using it to streamline incident response, speed root-cause analysis, optimize capacity, and improve developer productivity
Set vision & roadmap: Define a 12–18 month technical strategy for Messaging Infrastructure; translate it into quarterly, outcomes-based plans with clear tradeoffs and risks
Architect for scale & resiliency: Guide design for high-throughput streaming, durable queues, idempotent processing, multi-tenant isolation, and multi-region failover; champion observability-first development
Operational excellence: Establish SLOs and on-call practices; lead major incident reviews with a blameless, action-oriented posture; drive cost efficiency and capacity planning
Partner deeply: Work with Product, Security, Data, and GTM teams to align on customer requirements, roadmaps, and launch readiness; represent the platform in exec forums
Elevate engineering quality: Institutionalize design reviews, threat modeling, test strategies, and change management that reduce cycle time while protecting reliability
Talent & culture: Hire exceptional people, develop managers, and model urgency, ownership, and accountability—rewarding impact and raising the bar on what “good” looks like at scale
Continuously experiment with AI—testing tools, sharing learning, and championing new applications that responsibly accelerate org workflows and elevate quality
Qualification
Required
Platform-minded leader with a track record building/operating large-scale, low-latency distributed systems (messaging, streaming, or analogous high-throughput platforms)
Owner of outcomes. You connect engineering choices to business results—deliverability, latency, reliability, developer velocity, and cost—and hold teams accountable for moving those numbers
High-intensity, high-urgency operator who thrives in ambiguity, makes crisp tradeoffs, and ships ambitious, reliable systems on a predictable cadence
Inclusive people leader experienced in growing managers and senior ICs, building healthy on-call cultures, and scaling organizations across hubs
Strong partner & communicator who can translate complex systems into simple narratives for executives, customers, and cross-functional peers

Comprehensive range of health, welfare, and wellbeing benefits based on eligibility
